Dear ALL,
My question is related to the bioequivalence requirements of chiral drugs.
How to substantiate the use of achiral bio-analysis for racemic drugs with enantiomers having differing pharmacokinetics. Please also comments on the recommendations on the use of chiral/achiral methods as presented in the current Bioequivalence guideline (CPMP/QWP/EWP/1401/98 Rev.1).

Thanks in anticipation.

Regards
scorp
